Remove any unwanted fatty pieces from the pork. Season it well with salt and pepper on both sides.
Place all the onions and apples into the cooking pot of the pressure cooker. Pour in the apple juice and broth. Place the pork directly into all the juices.
Shut the lid and turn it to lock it into place.
Program the pressure cooker for 60 minutes by pressing the pressure cook time button until the green display shows 60, then press start. Make sure the pressure valve is set to airtight.
Once it's finished, release any remaining pressure and turn to open lid. The onions and apples will pretty much melt as soon as you stir the contents. Season with more salt and pepper if needed. Slice pork and serve over mashed potatoes or stuffing with some of the apple and onion sauce.
Note: You can always add your potatoes into pot before cooking if you want mashed potatoes. You can also throw in 2-3 Tablespoons of cornstarch to the juices at the beginning and mix it in before you turn it on to thicken your sauce. EnJOY!
